Walmart offers the LEGO Creator Ocean Explorer Set for $8.99. Choose in-store pickup to avoid the $5.99 shipping fee. That's tied with our mention from a month ago as the lowest price we've seen. (It's the best deal now by $5, excluding the below mention.) This 213-piece 3-in-1 set can be built as a ship with a movable crane, cargo plane, or large submarine.
